Hi, I just left my Doctor an hour ago who was OBVIOSLY having a bad day. I m being treated for HBP and was giving something I ve never had before. She gave me 4 different pills, the one in question is Vasotec. I m online to see what exactly it is. When I read the side effects, I fit all of them. I was feeling these before I took this new one, the other is Atenolol. Is it really important to notify her, cause I feel just fine other wise. It s not like her to give me something & not tell me what it s for. Thanks, Greg L.
